The next instant there was shown on the screen a picture of a boy setting off a giant fire-cracker under the chair of a sleeping man, who was depicted in the act of rising high into the air under the propulsion of the pyrotechnic. It was an irruption, but one not down on the program.


CHAPTER III

A QUEER CHARACTER

A chorus of laughter broke out among the students. It certainly was mirth-provoking to see that picture in place of the fire and clouds of smoke from the volcano. The class was in an uproar.

Professor Long waited patiently until the noise had subsided. He even allowed the wrong slide to remain on the screen. The boys finally ceased laughing. Then the instructor spoke.

“I presume that was done as a joke,” he said. “If so I think it was a very poor one. I don’t mind fun, but I like it in the right place. A certain amount is good, even in the schoolroom.”

His tone was sarcastic now, and Ned began to feel a little uncomfortable.

“You young gentlemen,” and he seemed to hesitate at the word, “you young gentlemen are sent here to learn. If you can do so and have fun, all right. I am paid by the city to teach you. I am expected to put a certain amount of knowledge into your brains. I can’t unless you let me. I’m not a magician.”
